About

BillSensor monitors SaaS subscriptions by detecting billing emails automatically and alerting users before renewal charges. It works with both Gmail and Outlook. For Gmail users, detection is passive — billing emails are read as they are opened in the inbox, with no Google account connection, no OAuth permission, and no setup required. Install the extension and it works immediately. For Outlook and Microsoft 365 users, a one-time read-only connection via the extension popup scans 12 months of billing history instantly, surfacing every active subscription including forgotten ones. Every detected subscription is scored from 1 to 10 based on dark billing patterns — how aggressively that tool makes cancellation difficult, whether it charges after cancellation, and whether it uses silent plan upgrades or seat additions without consent.

About

ChaChing is a Stripe Billing alternative that cuts SaaS subscription billing fees by 50%. At 0.35% of billing volume (vs Stripe Billing's 0.70%), SaaS companies save thousands annually without changing their payment processor. Stripe still processes every payment. ChaChing replaces only the billing management layer — subscriptions, invoicing, dunning, tax compliance, and analytics. Built on Kill Bill, the open-source enterprise billing engine (Apache 2.0) trusted by Fortune 500 companies invoicing billions annually since 2010. Kill Bill's core engineers are actively involved in ChaChing's development. Key features: - 0.35% billing fee (half of Stripe Billing) - Automated subscription management with smart dunning - One-off and recurring invoicing with payment links - Native TaxJar and Anara tax integrations (Avalara coming soon) - Real-time MRR, ARR, LTV, and churn analytics - REST API with OpenAPI spec and testing sandbox - Branded host
